Continuous space activities done by humans may be revolutionary for the future of mankind. Since the first explorations of humans outside the realm of the Earth, expeditions from the last 50 years has brought about significant amount of data that has changed how humans viewed all that is beyond our atmosphere.
The problem with this, on the other hand is the fact that continuous explorations of outerspace involves the generation of waste that cannot be easily solved. Known as space debris, these are human-caused pollution on the exosphere of the Earth.
According to a report from the European Space Agency (ESA), space debris can cause serious threats to humans. As more and more debris is created through time, scientists start to question and wonder how the problem can be solved. The ESA plans to hold a multinational conference to discuss this.
Based on this article, sizes of space debris vary significantly. Therr are some pieces with significant size and speed that must be monitored at all times. In the event that they enter the Earth's atmosphere or create impact with outgoing shuttles, it could mean disaster.
At any case, space debris is never a good thing. A report from The Verge has discussed that there are a number of tests and missions whose primary aim is to clean up all junk orbiting the Earth. To date, there seems to be a few that promises success but it would not be easy.
There are reports that in the event these large debris collide with each other, it will create smaller pieces of debris that has the possibilty of traveling at high speeds. These can then further collide with other space debris and the process will continue until there becomes a countless number of debris in space. In that case, they can also enter the Earth, disintegrate and create further pollution in the atmosphere.
