List 2 possible solutions for water shortage. cite your evidence
1. Solar-powered water purifiers
Hot climates suffer from water shortage the most. This is what drove an American schoolgirl to come up with a way to use solar power to purify water. When she was just 15, Deepika Kurup invented a way to use zinc oxide and titanium dioxide in containers that expose it to ultraviolet radiation and cleanse the water, making it suitable to drink. She was on the Forbes’ 2015 30-Under-30 in Energy list and was even awarded the U.S. Stockholm Junior Water Prize for her invention.
Her invention will help to address the fact that 1.1 billion people worldwide don’t have consistent access to clean drinking water.  Using Kurup’s invention and others like it, people will be able to make contaminated water drinkable so that they don’t have to depend on outside sources.
2. Leak monitors
German utility company, Albstadtwerke, has been using new software to pinpoint leaks and send the data instantaneously to a central data center. Showers, toilets and dripping taps are known to waste water, but the biggest problem is originates from pipelines that lead into the home.
The company believes that almost a third of water is wasted even before it reaches a home. The software, Zonescan Alpha is helping utilities around the world crack down on this inefficiency and massive waste of precious resources.
Why do you think a growing human population means a mass extinction event for Earth’s animals? Cite your evidence.
with So being said, so many people they have to have a place to stay. so taking trees down causes less habitable places for animals. mass slaughtering of meat causes less numbers of animals. without them to survive and thrive they cant repopulate as fast as we take and take.

What are 2 factors that complicate the food security issue?
The concept of food insecurity is complex and goes beyond the simplistic idea of a country's inability to feed its population. The global food situation is redefined by many driving forces such as population growth, availability of arable lands, water resources, climate change and food availability, accessibility and loss. The combined effect of these factors has undeniably impacted global food production and security. This article reviews the key factors influencing global food insecurity and emphasises the need to adapt science-based technological innovations to address the issue. Although anticipated benefits of modern technologies suggest a level of food production that will sustain the global population, both political will and sufficient investments in modern agriculture are needed to alleviate the food crisis in developing countries. In this globalised era of the 21st century, many determinants of food security are trans-boundary and require multilateral agreements and actions for an effective solution. Food security and hunger alleviation on a global scale are within reach provided that technological innovations are accepted and implemented at all levels.
