Hi and welcome to OSM!
It seems you added a football field as a highway, you might want to change it to a pitch:
leisure=pitch
Also, the name you gave it is descriptive, we tend to avoid that on OSM:
osm.wiki/Names

Hi and welcome to OSM!

Are these two park areas (and one park node) you've added actually parks by OSM definitions:
leisure=park

You might want to consider revising their tagging for more accuracy?

Nature reserve deleted, changeset needs to be reverted.

Pitch changed to recreation ground, baseball tag delete. Changeset needs to be reverted.

Total mess made out of paths. Changeset needs to be reverted.

Why did you delete this park? Changeset needs to be reverted.

There is already woods in this location. You don't need to change this nature reserve to also be woods.

This is a park. Please stop changing it. We will continue to change it back

This is a park, not a recreation ground or wood.
You really, really need to comment correctly on your changesets:
osm.wiki/Good_changeset_comments

Why do you keep changing pitches to recreation grounds? They are already tagged correctly as pitches,

Please read up on how to write better changeset comments so we can actually work out what you are trying to do here:
osm.wiki/Good_changeset_comments
Everything is not a recreation ground, please be more considerate in your mapping.

Why do you keep changing this golf course to a recreation ground? Tell us in your comments if you actually have a valid reason:

Please don't make fake edits to OSM. Several of your changes have been problematic. Remember that people use OSM for many purposes including emergency response and personal navigation.

This is a pitch. Please see the previous comments on your edits.

This is a golf course... it was tagged correctly.
leisure=golf_course
You really need to brush up on your tagging conventions before you continue to edit...

This is a pitch, why did you change it? leisure=pitch

Again, why did you change this from a park? What is your justification here? You need to work on your changeset comments, "Edit" is not useful to anyone else. osm.wiki/Good_changeset_comments

Recreation ground: landuse=recreation_ground

Park: leisure=park

I'm curious how you justify this change? Where are the pitches or nets?
