Climate change is primarily caused by human activities, such as the burning of fossil fuels, which release greenhouse gases into the atmosphere. These gases trap heat and cause the Earth's temperature to rise.

Oxygen is not a greenhouse gas. Greenhouse gases are gases that trap heat in the atmosphere, causing the Earth's temperature to rise. Water vapor is a greenhouse gas, but it is a natural component of the atmosphere and does not contribute to climate change in the same way that human-produced greenhouse gases do.

Extinction is the term used to describe the loss of biodiversity. It occurs when a species is no longer able to survive and reproduce in its environment, and its population declines until it eventually disappears.

Pollution is not a major threat to biodiversity in the same way that climate change, habitat loss, and invasive species are. While pollution can have negative impacts on individual species and ecosystems, it is not a primary driver of biodiversity loss.

Conservationists play a vital role in protecting the environment by raising awareness about environmental issues, advocating for policies that protect the environment, and conducting research on environmental issues.

The Paris Agreement is an international agreement that aims to reduce greenhouse gas emissions and limit global warming to well below 2 degrees Celsius, preferably to 1.5 degrees Celsius, compared to pre-industrial levels.

Natural gas is not a renewable energy source. Renewable energy sources are sources of energy that are naturally replenished and do not produce greenhouse gases. Natural gas is a fossil fuel that is extracted from the Earth and releases greenhouse gases when burned.

Mitigation is the term used to describe the process of reducing greenhouse gas emissions. It involves taking actions to reduce the amount of greenhouse gases released into the atmosphere.

The decline of the tiger population in India is not an example of a conservation success story. The tiger population in India has been declining due to habitat loss, poaching, and human-wildlife conflict.

Adaptation is the term used to describe the process of adapting to the impacts of climate change. It involves taking actions to reduce the vulnerability of human and natural systems to climate change.

Climate change is not a major cause of habitat loss in the same way that deforestation, urbanization, and agriculture are. While climate change can lead to changes in habitat, it is not a primary driver of habitat loss.

Resilience is the term used to describe the ability of an ecosystem to recover from disturbances. It is the capacity of an ecosystem to absorb and recover from stresses and shocks, such as climate change and habitat loss.

Using non-renewable resources is not a sustainable practice. Sustainable practices are those that do not deplete natural resources or harm the environment.

Sustainability is the term used to describe the concept of meeting the needs of the present without compromising the ability of future generations to meet their own needs. It involves taking actions that protect the environment and ensure that resources are available for future generations.
