There are a number of environmental factors that can have an affect on humans. Specifically woman who are pregnant, there are teratogens, which are,drugs, radiation, or enviornmental factors that can harm the fetus. This website gives a list of the different teratogens known in the world. There are over 200 of them and they can't all be avoided, but sometime it's nice to just know what's harmful out there. http://msds.chem.ox.ac.UK/teratogens.HTML
Some useful chemical changes are when a solid changes into a liquid. Such as when ice melts it is turned into water.Sorry but I am afraid that is wrong.Freezing, melting and evaporation including sublimation, i.e., Changes of State, are all physical, not chemical, changes.As for "useful" chemical changes.... Almost all biological processes, the conversion of fuel to its oxides etc with consequent release of heat &/or light, the list goes on!

As we age, our bodies go through certain changes. We live in a harsh environment here on the Earth. Some symptoms of aging can be attributed to environmental factors such as exposure to radiation from the sun, air pollution and chemicals in the food and water which we ingest. Still others involve oxidation of the molecules of our bodies by harmful 'free radicals' which do damage to our DNA. The list goes on, I'm sure. The biggest factor is our lifestyle. Our diet, activity level and harmful chemicals we choose to indulge (alcohol, tobacco, drugs).

A linked list is useful for data which will be changed very often. The linked nature of linked lists makes them ideal for inserting and removing elements, as it requires only changing one or two pointers.

The environment can only be harmed if there is irresponsible and careless management practices of any sort of agricultural methods, from tillage to grazing. You can list all the ways in which any sort of agricultural practice, commercial, hobby or subsistence, can harm the environment you want but you cannot get away from it. There are many misconceptions about agriculture out there, many that are considered by the general public to be "harmful" to the environment, all due to misconstrued facts and exaggerated statistics spread around by the media.
