As you grow older you will probably become less able to work and earn money. This is normal. This does not make it good or something for you to look forward to. There have been scandals in the USA where it was (re)discovered that elderly people were forced to buy dog food to eat themselves because of not being able to afford meat for humans.
Social safety nets, that give food to people who would have starved to death in the past, have increased worldwide. You may be depending on one of these safety nets to keep eating as you age.
This is not a good idea. Climate change is already making food prices go up all over the world. This will get much worse. As prices continue to rise, there will be more need for the food from social safety nets because of more poor people needing food, and less food and money to spare for social safety net programs.
When you do things to stop climate change you are protecting your own food supply, now and in the future.
We need more people who understand, care about, and are willing to act to stop climate change. It is in your own best interests to be one of these people. Your own future depends on it.
Climate change is raising the average temperature of the whole Earth. One of the easily predictable results of a rise in the Earth's average temperature is drought. Your food supply will be harder to keep coming to you when there are more droughts.
Plants need water. If you want to eat plants or animals that eat plants, you need water for those plants. This is true even if your food does not come from your own area or country.
In 2012 the United States had a very bad drought. Ninety percent (90%) of the cropland in the USA had a drought last year. This used up all of the food stored up by the government to give to poor people. It was not replaced. Food banks all over the country are already running out of food to give poor people from only one year of drought.
Since the United States is a food exporting country, this has driven up food prices all over the world. This situation will last at least the rest of this year without another drought, because of limited supplies to food manufacturers in the United States. We can expect a continued rise in overall food prices for the rest of this year.
This is just a sample of what we face with our food supply as droughts occur
more often and in more places in the world. If you want to keep eating, you need to learn more and take action to stop making climate change worse.
