The Human Footprint measures the ecological assets that a population requires for consumption. This includes our food, clothes, the fuel we use for cars, building materials for our homes, etc...

Measure
The global hectare (gha) is the ecological footprint unit.

Portugal is ranked 57th in the world countries total ecological footprint (gha).

Today humanity uses the equivalent of 1.75 Earths to provide the resources we use and to absorb our waste. This means it now takes the Earth one year and eight months to regenerate what we use in a year.

It's a fact that the humanity has harmed the environment for greedy and selfish reasons. However, we believe that there are people  who want to help make a difference. Through technologies and creativity, many inventions were created to help the environment. In this case, we brought together some devices that help improve the water quality around the world everyday.

Mr. Trash Wheel is a semi-autonomous trash interceptor that is placed at the end of a river or stream.
Far too lazy to chase trash around the ocean, Mr. Trash Wheel stays put and waits for the waste to flow to him. Sustainably powered and built to withstand the biggest storms, Mr. Trash Wheel uses a unique blend of solar and hydro power to pull hundreds of tons of trash out of the water each year.

This is an education and filtration tool developed by a group of students and the organisation Water is Life. It consists in a book that provides basic water and sanitation advices. At the same time, due to its “scientific coffee filter”, it can filter 99.9% of the bacteria in the water.
The Drinkable Book can provide to his reader clean water for four years .

The Seabin is an ocean garbage bin that works like a large pool skimmer. It is powered from shore—requiring access to electricity—and uses a 110 or 220 V motor to pump water and create a vortex, sucking debris out of the water and into a catch-bag within the bin, pushing the cleaned water back out. Seabin has been installed around the world and has won 8 major awards.

LifeStraw is an award-winning innovative product that allows people to filter water anywhere. It uses advanced hollow fiber technology to filter water, allowing users to simply suck water through it. This device has been distributed around the world and each straw can filter up to 5 years of clean water.

Water pollution is a big environmental issue  that has a huge impact on humankind, since we all need water to survive. When we pollute water, we are not only prejudicing ourselves but also destroying ecosystems and in consequence of it, damaging biodiversity. For example, toxic and chemical waste that gets into our waterways, can lead to human illness and poison the marine life.

With this work, we learned many things about the water in our planet and the environment. Namely, the concept of Human Footprint, the devices that are changing the world and the impact of the human action on earth.

From our point of view, our actions have a big impact on the environment and therefore we should be aware of their consequences to other living beings and the planet.
By living in a modern and technology-driven society, we should use that knowledge in our favor and benefit, as a way to face today's world problems.
