Here's the corrected version of the passage with the identified mistakes corrected:

---

We can all **imagine** an intrepid explorer, cutting his way through a thick jungle. But what exactly is a jungle, and where are the great jungles of the world? One definition of jungle **is** an area of thick tangled plant growth at ground level. But, as this could also refer to your garden when you haven't had time to cut the grass for a week or two, the term 'jungle' is generally reserved **to** describe dense rainforests in tropical regions. However, some large forests in subtropical or even warm temperate regions are sometimes described as jungles. The major jungles are **found** in Central and South America, Africa, and Southeast Asia. **There are also** jungles in North Australia, and even parts of the USA, such as Florida. Although it is rarely as hot **as** in the desert, the temperature in the jungle is always warm. Jungles are also categorised by their heavy rainfall, their darkness on ground level - due to the inability of sunlight to break through the thick vegetation - and the wide variety of plants and animal species **found** in them. As has been widely reported lately, the great jungles of the world are now facing their greatest danger: humans. Each year, somewhere between seven and twenty **million** hectares of jungle are destroyed.
