- Which Book First Raised Awareness About The Environmental Issues And Influenced The Society To Change?
The book that first raised widespread awareness about environmental issues and significantly influenced society to change is “Silent Spring” by Rachel Carson. Published in 1962, the book exposed the dangers of pesticides, particularly DDT, and their harmful effects on wildlife, ecosystems, and human health.
“Silent Spring” is credited with sparking the modern environmental movement by bringing attention to the need for more sustainable practices and policies regarding the use of chemicals in agriculture. It led to a shift in public consciousness about the importance of environmental conservation and helped lay the groundwork for laws that regulate pesticide use, such as the establishment of the Environmental Protection Agency (EPA) in the United States.
The book’s impact was profound, as it not only highlighted environmental degradation but also encouraged a broader conversation about the relationship between humans and the natural world.
2. Where Does The Most Breathable Oxygen In The World Come From?
The most breathable oxygen in the world primarily comes from the ocean, particularly from phytoplankton. These tiny marine plants, along with algae and seaweed, perform photosynthesis, absorbing carbon dioxide and releasing oxygen as a byproduct.
In fact, phytoplankton are responsible for producing about 50-80% of the oxygen on Earth. They are the foundation of the ocean’s food web, and their oxygen production plays a crucial role in maintaining the balance of atmospheric gases.
Forests, particularly the Amazon Rainforest, also contribute significantly to oxygen production on land, but the ocean is by far the largest source of breathable oxygen on the planet.
3. Which Country Has The World’s Greatest Biodiversity?
The country with the world’s greatest biodiversity is Brazil. Brazil is home to a staggering variety of plants, animals, and ecosystems, particularly due to its vast Amazon Rainforest, which is often called the “lungs of the Earth.” This region harbors more species than any other place on the planet.
Brazil’s biodiversity includes:
- Thousands of species of plants, insects, and animals.
- A wide range of ecosystems like tropical rainforests, wetlands, and savannas.
- Endemic species, such as the Golden Lion Tamarin and the Jaguar.
While other countries like Indonesia, Colombia, and Madagascar also boast remarkable biodiversity, Brazil’s diversity is particularly exceptional due to its size and the variety of habitats within its borders.
4. We Know That 70% Of Earth Is Covered In Water But Out Of This What Is The Percentage Of Freshwater?
Although 70% of Earth’s surface is covered in water, only about 2.5% of that water is freshwater. The rest is saltwater found in the oceans.
Of that 2.5% of freshwater, the majority (about 68.7%) is trapped in ice caps and glaciers, leaving a small portion (around 1.2%) available in rivers, lakes, and groundwater for human use.
5. What Are The Top Three Causes Of Climate Change
The top three causes of climate change are:
- Greenhouse Gas Emissions: The burning of fossil fuels (like coal, oil, and natural gas) for energy, transportation, and industrial activities releases large amounts of carbon dioxide (CO2) and other greenhouse gases (GHGs) into the atmosphere. These gases trap heat, causing the planet to warm, a phenomenon known as the greenhouse effect.
- Deforestation: Cutting down forests, especially tropical rainforests, reduces the number of trees that can absorb CO2 from the atmosphere. This increases the concentration of greenhouse gases, contributing to global warming.
- Agriculture and Livestock Farming: Agricultural practices, including the use of synthetic fertilizers, release methane (a potent greenhouse gas) into the atmosphere. Livestock farming, particularly cattle, also produces significant amounts of methane through digestion (enteric fermentation), further accelerating climate change.
These human-driven activities have drastically increased the concentration of greenhouse gases, leading to a rise in global temperatures and more extreme weather patterns.
6. What Is The Main Goal Of The Paris Agreement?
The main goal of the Paris Agreement is to limit global warming to well below 2°C above pre-industrial levels, with efforts to limit the temperature increase to 1.5°C. This goal aims to reduce the impacts of climate change, such as extreme weather events, rising sea levels, and disruptions to ecosystems and economies.
To achieve this, the agreement calls for:
- Reducing greenhouse gas emissions globally.
- Increasing climate resilience and adapting to the effects of climate change.
- Providing financial support to developing countries to help them mitigate and adapt to climate impacts.
The Paris Agreement emphasizes that countries must work together and set national climate targets (known as Nationally Determined Contributions, or NDCs) to meet these goals and regularly update their commitments to make progress toward a sustainable future.
7. When Was The Paris Agreement Signed
The Paris Agreement was signed on December 12, 2015, during the United Nations Climate Change Conference (COP21) in Paris, France. It was later opened for countries to officially sign and ratify, and it entered into force on November 4, 2016.
8. How Many Species Of Animals Live In The Ocean?
The exact number of animal species living in the ocean is difficult to determine, but scientists estimate that there are around 230,000 known species of marine animals. These include fish, mammals, invertebrates (like jellyfish and crustaceans), and various other organisms.
However, it’s believed that the actual number of marine species could be much higher, with many still undiscovered, especially in deep ocean ecosystems. Some estimates suggest that the total number of marine species could reach over 2 million once all undiscovered species are accounted for. The ocean remains one of the most biodiverse and least explored areas on Earth.
9. What Are The Largest Living Structures On Earth?
The largest living structures on Earth are coral reefs, with the Great Barrier Reef being the most famous and the largest of them all.
- Great Barrier Reef: Located off the coast of Australia, it stretches over 2,300 kilometers (1,430 miles) and is made up of thousands of individual coral reefs and islands. It’s so large that it can be seen from space.
Coral reefs are made up of colonies of tiny coral polyps that work together to form massive structures. These reefs support diverse marine life and are vital for the health of ocean ecosystems.
Besides coral reefs, other large living structures include the Amazon Rainforest, but that’s terrestrial, not marine. The Great Barrier Reef, though, remains the largest living structure on Earth.
10. Which Sector Emits The Maximum Greenhouse Gases?
The energy sector is the largest emitter of greenhouse gases (GHGs), accounting for roughly 73% of global emissions. This includes:
- Burning fossil fuels for electricity and heat production (such as coal, natural gas, and oil).
- Transportation, which relies heavily on fossil fuels like gasoline and diesel for cars, trucks, planes, and ships.
- Industrial processes that use energy-intensive methods, such as cement production and steel manufacturing.
The energy sector is the primary source of carbon dioxide (CO2) emissions, which is the most prevalent greenhouse gas contributing to climate change. Reducing emissions in this sector is critical to mitigating global warming.
11. Where Did The First Earth Day Celebration Take Place?
The first Earth Day celebration took place on April 22, 1970, in the United States. It was organized by Senator Gaylord Nelson as a nationwide environmental protest to raise awareness about environmental issues, such as pollution and conservation. The first Earth Day saw millions of people across the country participating in rallies, demonstrations, and educational events to promote a cleaner, healthier planet.
The event was so successful that it helped inspire the creation of environmental laws in the U.S. and led to the establishment of the Environmental Protection Agency (EPA). Today, Earth Day is celebrated globally, with events taking place in many countries to raise awareness and take action on environmental issues.
12. What’s The Theme Of Earth Day 2022?
The theme of Earth Day 2022 was “Invest In Our Planet.” This theme emphasized the need for individuals, businesses, and governments to take action to protect the environment by investing in sustainable practices, renewable energy, and green solutions to address the climate crisis and promote a healthier planet for future generations. The focus was on making bold, transformative changes to build a sustainable future.
13. Who Founded Earth Day?
Earth Day was founded by Senator Gaylord Nelson of Wisconsin. He came up with the idea in 1969 to raise public awareness about environmental issues, such as pollution and conservation. Nelson was inspired by the growing environmental movement and the need for greater government attention to environmental problems.
He teamed up with activist Dennis Hayes, who helped organize the first Earth Day on April 22, 1970. The event brought millions of people together across the United States, making it the largest public demonstration at the time and helping to spark the global environmental movement.
