The major environmental concerns in Oceania and Australia re the overfishing and the invasive species.
Explanation:
Australia and Oceania, as pretty much every place in the world, have some big environmental problems. Unlike the rest of the world, this region doesn't really have problem with deforestation, but it has big problems with overfishing, as well as with invasive species. The overfishing and the invasive species combined, manage to create huge problems, especially when it comes to the protection of the native species and keeping their numbers stable.
The overfishing has occurred because of the higher demand for fish. It is not just the local population that uses the fish extensively in its diet, but also there is huge demand worldwide, so lot of fish is actually for export. This has resulted in badly damaging the fish populations, and bringing some species on the verge of existence. The invasive species, have been brought in order to solve some problems, especially when it comes to food supply for the humans, but it turned out that they are fatal toward the local flora and fauna. Species like the cat, fox, camel, pigs, have managed to outcompete the indigenous fauna and lead to its endangering.

Answer:
The cost price is Rs.500
Explanation:
<em>I'll approach this question by taking the statements in the question, one after the other</em>
Let the cost price be represented by CP
From the first statement:
Sanjay made a loss of 25%
The selling price (SP) is as follows;
Convert percent to fraction
Get decimal equivalent
From the second statement:
If the selling price was increased by 175%, Sanjay would make a profit of 10%
Hence; The new selling price is
The selling price can also be calculated from the profit
Convert percent to fraction
Get decimal equivalent
Equate both values of SP (SP = SP)
Collect Like Terms
Divide both sides by 0.35
<em>Hence, the cost price is Rs.500</em>
