No Clean Water: We may live on a water planet, but 97.5% of that water is ocean and other undrinkable salt-filled sources. Only 2.5% of the water on this planet is fresh, and of that, 1% is either too polluted to be consumed or entirely unreachable. Much of it remains frozen in the form of polar ice caps. All told, less than 1% of the planet’s freshwater resources are available for consumption.
Lower Life Expectancy: Thanks to medical intervention, human beings can live to be up to 100 years old — as long as they live in developed countries where they have access to that medical care. One study, done by researchers at Harvard, found that the majority of population increases over the next 40 years or so will be in less developed countries.
Climate Change: We’ve been seeing the results of climate change firsthand in the dramatic weather patterns of 2017 — multiple category five hurricanes, dramatic wildfires and floods, and other atypical weather patterns that are threatening both lives and property.
Answer:
Diatoms
Explanation:
Diatoms are a photosynthetic eukaryotic phytoplankton that virtually found in all waterways, fresh waters and oceans, and also in most soils on earth. Diatoms play a very important role in the global carbon cycle. Diatoms are single-celled algae that has a characteristics cell wall that is made up of transparent opaline silicia that are elegantly sculpted.
When diatoms die, their shell or skeleton that is composed of silica, do not decay, but settle at the bottom of oceans as sediments to form what is often referred to as diatomaceous earth. It is this diatomaceous earth deposit that is then converted to diatomite powder, which is used as pesticides against insects such as ants, cockroaches, bedbugs and some other pests.
