FAST FACTS
On climate and nature
1. Healthy ecosystems can provide 37 per cent of the mitigation needed to limit global
temperature rise. Damaged ecosystems release carbon instead of storing it.
2. Approximately 25 per cent of the globe’s greenhouse gas emissions come from
land clearing, crop production and fertilization, with animal-based food contributing
75 per cent of that.
3. With global warming of 1.5°C to 2°C , the majority of terrestrial species ranges are
projected to shrink dramatically. Changes in ranges can adversely affect species
conservation, greatly increase local species turnover and substantially increase the
risk of global extinctions.
4. Climate change has been linked to greater risks from zoonotic diseases. For some
contagions, increases in temperatures or rainfall can dramatically affect the life
cycles of either the pathogen or its vector – the intermediate species that spreads the
disease from the original host to humans.
5. Coral reefs are particularly vulnerable to climate change and are projected to
decline to 10-30 per cent of former cover at 1.5°C warming and to less than 1 per cent
of former cover at 2°C warming.
6. More than 80 per cent of the human diet is provided by plants. Only three cereal
crops – rice, maize and wheat – provide 60 per cent of energy intake.
7. Fish provide 20 per cent of animal protein to about 3 billion people.
8. Roughly 500 million people live in areas that experience desertification. Drylands
and areas undergoing desertification are more vulnerable to climate change and
extreme events including droughts, heatwaves and dust storms.
9. Up to 80 per cent of people living in rural areas in developing countries rely on
traditional plant-‐based medicines for basic health care.
10. Less than 1 per cent of total land is used for mining, but the industry has
significantly negative impacts on biodiversity, emissions, water quality and human
health.
11. The $345 billion provided as global subsidies for fossil fuels results in $5 trillion in
overall costs, including in terms of the deterioration of nature.

Here is a relevant blog comment in English language:
“Thank you for sharing this insightful post on the impact of climate change on our planet. It’s alarming to see how human activity has led to the destruction of ecosystems and the release of carbon, which is further exacerbating global warming. The fact that healthy ecosystems can provide 37 per cent of the mitigation needed to limit global temperature rise is an eye-opener.
I also appreciate the focus on the role of businesses in addressing climate change. It’s important to acknowledge that businesses are not the enemy, but can be a part of the solution. By working together, we can find innovative ways to protect our planet and promote sustainable development.
One area that I believe needs more attention is the impact of climate change on poverty. As you mentioned, climate change can increase the risk of zoonotic diseases and negatively impact food security, which disproportionately affects people living in poverty. It’s crucial that we prioritize the needs of marginalized communities in our efforts to address climate change.
Overall, this post highlights the urgent need for collective action to take better care of our planet and end poverty. Let’s rally together to make a difference.”
