Science- Organisms Under A Microscope

In Science, we worked with microscopes to see microscopic organisms. Above is a video of the Tubifex worm under a microscope. I see how they have a transparent outside, and red on the inside.

Above is a video of Turtle Water. I notice mainly green blotches and small tiny green moving organisms. 


Global Water Crisis:
The Global Water Crisis is a crisis about how so many people lack water, and get water related diseases. According to the World Bank and World Health Organization, 2 billion people lack access to clean water, and 1 billion do not have enough water to meet their daily needs. Organizations are trying to help with this by doing things like building wells in countries that face the water crisis.
Water is extremely important for humans; first of all our bodies are 60% water; and we use water for things like cooking, cleaning, etc.
Today, people waste water a lot. We waste water when we don't drink it, but more consequentially, we waste a lot of it on produce. The average hamburger takes 2,400 liters or 630 gallons of water to make.
Dirty water can also cause various diseases. Every minute, one child dies from a water related disease, and 1 out of every 5 child deaths is from a water related disease.
