What evidence is there that the endangered species act is causing harm to species????
Juliette [100K]

Answer:

There is strong and increasing evidence the Endangered Species Act is causing widespread harm to the species it is supposed to protect-to the extent the Act may be doing more harm than good. The Act makes otherwise normal and legal forms of land and resource use illegal, such as farming, home building and cutting timber. The Endangered Species Act’s severe penalties-$100,000 and/or 1 year in jail for harming a single species or even unoccupied habitat that is deemed suitable-turn species in to liabilities. As a result, landowners seek to reduce their liabilities in a number of ways.

Diferença entre soluções líquidas e líquidos puros
vladimir1956 [14]

Portuguese version:

Não falo português mas:

Uma solução é formada quando algo é adicionado ou dissolvido em um líquido. Você faz uma solução quando adiciona sal ou açúcar a um copo de água. ... Desde que um líquido seja feito de uma única substância, ele permanece puro e é chamado de líquido. Quando algo é adicionado a ele, ele se torna uma solução.

English version: I don't speak Portuguese but:

A solution is formed when something is added or dissolved in a liquid. You make a solution when you add salt or sugar to a glass of water. ... As long as a liquid is made of a single substance, it remains pure and is called a liquid. When something is added to it, it becomes a solution.

Spanish version: No hablo portugues pero:

Se forma una solución cuando algo se agrega o se disuelve en un líquido. Usted hace una solución cuando agrega sal o azúcar a un vaso de agua. ... Mientras un líquido esté hecho de una sola sustancia, permanece puro y se llama líquido. Cuando se le agrega algo, se convierte en una solución.

fReNcH vErSiOn: Je ne parle pas portugais mais:

Une solution se forme lorsque quelque chose est ajouté ou dissous dans un liquide. Vous faites une solution lorsque vous ajoutez du sel ou du sucre à un verre d'eau. ... Tant qu'un liquide est constitué d'une seule substance, il reste pur et s'appelle un liquide. Quand quelque chose y est ajouté, cela devient une solution.

Ok, terminei, tchau.

Okay, I'm done, Bye.

Bien, he terminado, adiós.

D'accord, j'ai fini, au revoir.
