The role of satellites
This page exists to demonstrate the countless benefits already provided by the implementation of various satellites, whether these be toward climate change, healthcare, or disaster relief. This page will also explore the potential future benefits from the development of new satellite technologies.
Utilising Satellite Technology for Wildlife Conservation
High-resolution remote sensing images have provided conservationists and ecologists with the ability to accurately monitor illegal mining, to monitor wildlife populations, to rapidly detect deforestation activities and other alterations being made to the landscape. Earth imagery provided by satellites is collected frequently, globally, and at an increasingly higher quality.
Arctic Tundra Going Green
A study led by a team of scientists from the Northern Arizona University in Flagstaff discovered by analysing high-resolution satellite imagery, that 37.3% of the Arctic Tundra grew significantly greener between 1985-2016. The Changing Arctic Tundra A Tundra biome is commonly portrayed as having a permanently frozen subsoil known as the permafrost, little precipitation and low biotic diversity.
Using Satellite Technology to Monitor Climate Change
Satellite technology has the ability to measure Earth’s temperature, greenhouse gas emissions, sea levels and atmospheric gases, which are all imperative to the awareness and improvement of climate change and the prediction of the future of the Earth.

Tracking Ocean Plastic Pollution using Satellite Technology
The European Space Agency is manufacturing satellites that identify discarded plastics such as water bottles, fishing nets, and grocery bags, all the while monitoring the concentration, movement, and origin of plastic debris across the world’s oceans. Until the development of such satellites, most of this debris has previously been found using alternative methods, such as towing underwater cameras that locate and take images of debris found deeper underwater, and even going as far as to swim through the debris. Scientists are working on Earth observation satellites that will track plastic debris in the ocean from space by searching for the plastic’s reflected light signature in the water.
