Water''s solvency is why the water that we use is rarely pure; it usually has several minerals dissolved in it. The presence of these minerals is the difference between hard water and soft water . Hard water usually contains a lot of calcium and magnesium, but may also contain metals.
Litter in our seas — European Environment Agency
Around 70 % of our planet is covered by oceans and marine litter can be found almost everywhere. Marine litter, plastics in particular, pose a threat not only to the health of our seas and coasts, but also to our economy and our communities. Most marine litter is generated by land-based activities. How can we stop the flow of litter into our seas? The best place to start tackling this global
