Some people sure hope so.Global warming is caused by greenhouse gases that trap heat in the air, increasing the Earth's overall temperature. Because humans are releasing more and more of these gases into our atmosphere, global warming will most probably get worse in the future. This will have many terrible effects. For example, ocean temperatures will rise and polar ice caps will melt. This will cause ocean levels to rise, which will be a serious problem for people living on islands and in coastal areas.One type of greenhouse gas is carbon dioxide. Carbon dioxide is usually removed from the air by trees during a process photosynthesis. This is when green plants make food using energy from the sun. However, because of deforestation, many of the trees we rely on to reduce carbon dioxide levels are disappearing. Environmental groups have tried to stop farmers and companies from cutting down too many trees, but unfortunately, they haven't had much success.Because of this, some environmental groups are trying a different approach: they’re planting new trees to replace the ones that were cut down. One such group is One Tree Planted. One Tree Planted helps plant young trees all over the world at just one dollar a tree. In 2019, they planted nearly 4 million new trees. They hope that these trees will one day grow up and play an important role in helping to reduce the amount of carbon dioxide in the air.One baby tree certainly won’t make much of a difference in our fight against global warming. But if we continue to plant more and more trees, maybe someday, we’ll have enough to bring down the Earth’s carbon dioxide levels by a meaningful amount.
