The world is getting warmer.Human activity is the main reason for this，the United Nations （UN） said.For example，people use fossil fuels （化石燃料）like coal and oil.They give off a lot of greenhouse gases （温室气体）（especially CO ₂） into the air.This warms the earth.

As a result，many animals are dying out， （A）______ as penguins （企鹅）and polar bears.It will soon make a difference to us as well. （D） Sea levels will rise and many cities along the sea will disappear.

To fight climate change，countries around the world need to work together.China is now taking the lead.It has set new goals to deal （B）______ this problem.It will bring its total greenhouse gas emissions （排放）to a peak （峰值）before 2030. （C） Itwill also achieve carbon neutrality （碳中和）before 2060，Xinhua reported.

Being carbon neutral means taking away the same amount of CO ₂from the air as you put into it.It was set as an initiative （倡议）by the UN in 2015.

There are two ways to get to carbon neutrality.One is to plant more trees to absorb （吸收） the emitted （排放的）CO ₂.The other is to stop CO ₂emissions altogether by using non﹣fossil（非化石）fuels.Examples of these fuels include electricity and wind energy.

Over 20 countries and regions have carbon neutrality goals.Most of them will plant more trees.So will China.If China can realize its goal，it will lower global （全球的）warming by around 0.2°C to 0.3°C alone，according to Climate Action Tracker （气候行动追踪组织）.
