How do human activities affect the environment?
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation.
Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water..

Who is responsible for global warming?
One of the first things the IPCC concluded is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, buildings, factories, and power plants. The gas responsible for the most warming is carbon dioxide, or CO2.

Which country has the lowest carbon footprint?
TuvaluYou have probably never heard of Tuvalu before, and that is a big part of the reason why it has the lowest carbon footprint on the planet. Their current carbon footprint rests at zero MtCO₂, and they plan to continue this trend by doing away with fossil fuels altogether.
Which country has the greatest danger from global warming?
The Arctic, Africa, small islands and Asian megadeltas are regions that are likely to be especially affected by future climate change. Africa is one of the most vulnerable continents to climate variability and change because of multiple existing stresses and low adaptive capacity.
What is the largest source of co2 emissions globally?
Energy consumption is by far the biggest source of human-caused greenhouse gas emissions, responsible for a whopping 73% worldwide. The energy sector includes transportation, electricity and heat, buildings, manufacturing and construction, fugitive emissions and other fuel combustion.
What are the causes of global warming?
Global warming is an aspect of climate change, referring to the long-term rise of the planet’s temperatures. It is caused by increased concentrations of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, deforestation and farming.
