The president of our chapter of Earth Guardians also gave a presentation on food waste! A lot of pollution and carbon dioxide is emitted for food production, just for a large portion of that food to go to waste. Take a look at the presentation to see the effects of food waste and how you can help solve the problem.
A video is included in the presentation, but if you can't access it through the link on the presentation, it is also attached below: https://www.youtube.com/watch?v=ishA6kry8nc
During the first Earth Guardians meeting of the year, our club president gave a short presentation on the 3Rs. Reducing, Reusing, and Recycling is a key principle to living more sustainably.
I gave a presentation in my Earth Guardians club about heat waves and wildfires. These events are increasing as global warming ramps up, and they cause serious problems around the world.
Heat Waves and Wildfires presentation
In the presentation, it mentions that heat waves can be caused by a high-pressure system. This is a brief summary of how high-pressure systems cause heat waves:
The Earth absorbs heat from the sun, and then the ground warms the surrounding air. Therefore, the atmosphere is warmer closer to the earth. Normally, air cycles around the globe, and warm air will rise above cold air because it is less dense. As the warm air rises, it will continually cool until the air mass starts to descend again. Water vapor in the warm air will also rise until the air cools and the water condenses into clouds. However, high-pressure systems act like a ceiling that forces warm air downwards. This means that the air mass just keeps getting hotter and hotter because it is trapped near the earth, its source of heat, which then leads to a heat wave. There is also very little to no rain during a heat wave because all the water vapor is trapped near the earth with the warm air, so the vapor cannot cool down enough to condense into clouds.
All living organisms have a range of climate conditions they can tolerate, so heat waves can cause illness or death for many living things, including humans.
